Answer:
A. Ernest Rutherford
B.Bohr
C. Eugen Goldstein
D.. Santiago Ramon y cajal
E.john Dalton
F.isobars - a line drawn on a weather map connecting points of equal pressure is called isobars.
example.. argon 40
potassium 40
.two differences between isobars and isotopes.
isobars are those elements which have different atomic number but the same mass number. while isotopes are those elements having the same atomic number and different mass number..
two uses of isotopes.
uranium 235 - for nuclear fission and as fuel in unclear reactors.
# an isotope cobalt - used In the treatment for cancer
# an isotope iodine - used in treatment of goiter.
Since it is an element. It is 1.01g/mol as per the periodic table
The gas however H2 is diatomic which has a mass of 2.92
Hello
The conclusion we can make about these two organisms,
Is C. They're different species with no evolutionary relationship.
Thank you, and Goodbye.
Democritus *suggested* the existence of the atom, that everything was made up of tiny particles, but wasn't really able to get more specific than that. Dalton also theorized that everything was made up of indivisible particles, but went further basing his theory on actual scientific principles, such as the Law of Conservation of Mass and the Law of Constant Composition. He also said that atoms weren't created or destroyed in a chemical reaction, just rearranged. There's more to it than that, but basically, Dalton's theory was based more on science while Democritus' theory was too general to be useful in chemical situations.
Reactivity is the tendency of a substance to undergo chemical reaction, either by itself or with other materials, and to release energy.
